Hotel Tonight Referral Code: FNISAR

Looking for a working HotelTonight referral code in the UK? New HotelTonight customers can use the referral code FNISAR to receive £20 off their first eligible hotel booking over £100.

HotelTonight is a hotel-booking app designed to make finding and booking discounted hotel rooms quick and straightforward. Although it became known for last-minute hotel deals, the app now lets travellers reserve rooms for tonight, next week or up to 100 days in advance.

FNISAR

Download the HotelTonight app, create a new account and enter FNISAR in the Promo Code section to claim £20 off your first qualifying booking over £100.

What Is HotelTonight?

HotelTonight is a mobile-focused hotel-booking service that helps travellers find rooms at selected hotels, inns, guest houses, resorts and other accommodation.

The app originally concentrated on unsold rooms available for same-day stays. Hotels would offer reduced rates rather than leave rooms empty, giving flexible travellers an opportunity to find potentially attractive last-minute prices.

HotelTonight has since expanded beyond same-day bookings. Depending on availability, customers can now search for:

Hotels for the same evening
Last-minute weekend breaks
Accommodation for upcoming business trips
Rooms for events or nights out
Short UK staycations
International hotel stays
Bookings made up to 100 days in advance

HotelTonight aims to provide a more curated selection than some of the largest hotel comparison platforms. Instead of presenting an enormous list of properties, it highlights hotels that match the selected destination, dates and preferences.

The app lets customers book stays of up to 14 nights and reserve as many as four rooms in a single booking. Same-day rooms can generally be booked until 2am local time during the first night of the stay.

How to Use the HotelTonight Referral Code FNISAR

Claiming the HotelTonight new-customer discount should only take a few minutes.

Step 1: Download the HotelTonight app

Download HotelTonight from the Apple App Store or Google Play Store.

Some rates and app-specific features may not be available through the standard HotelTonight website, so using the mobile app is recommended.

Step 2: Create a new account

Open the app and register for a new HotelTonight account.

Use an email address you can access because your booking confirmation, receipt and important information about your stay may be sent to it.

The FNISAR referral code is intended for new customers. If you have previously made a HotelTonight booking using the same account, device or payment method, the introductory discount may not be accepted.

Step 3: Enter the referral code

You can normally enter a HotelTonight promo code in one of two places:

Open your account profile, find the Promo Code or Redeem option and enter FNISAR.
Add FNISAR in the Promo Code box while completing your first booking.

HotelTonight confirms that codes can be entered at checkout or saved through the account’s promotional-code section. Codes can generally be used once, and separate promotions cannot normally be combined.

Step 4: Search for a hotel

Enter your destination, check-in date, check-out date and number of rooms.

Use the available filters to narrow the results by requirements such as:

Price
Location
Hotel style
Wi-Fi
Parking
Pet-friendly accommodation
Guest rating
Cancellable rates
Number of rooms

Step 5: Choose an eligible booking over £100

Your first eligible booking must be over £100 to receive the £20 discount.

The required value will generally relate to the qualifying room price and may exclude taxes, mandatory charges and additional hotel fees. Check the total shown in the app and confirm that the referral code has been accepted.

Step 6: Review the cancellation terms

Before paying, check whether the rate is:

Refundable
Partially refundable
Cancellable until a particular deadline
Non-refundable and non-cancellable

Many HotelTonight rates are sold on a non-refundable basis. Do not assume that a booking can be changed simply because the stay is several weeks away.

Step 7: Confirm the discount

At checkout, look for the £20 promotional discount in the price breakdown.

For example, if the eligible room price is £120 and the code is successfully applied, the promotional reduction should bring that part of the price down to £100. Taxes, local charges or other fees may still be added.

Step 8: Complete your booking

Check the following details before confirming:

Hotel name
Hotel address
Check-in and check-out dates
Number of guests
Number of rooms
Room type
Cancellation policy
Taxes and fees
Final amount payable
Application of the FNISAR code

Once satisfied, confirm the reservation and retain the booking email.

Why Use the HotelTonight Referral Code?

The main benefit is simple: £20 off an eligible first booking over £100.

A £20 saving represents a meaningful discount on a short hotel stay. The value depends on the qualifying booking price:

Eligible booking value	Referral discount	Price after discount*	Effective saving
£110	£20	£90	18.2%
£120	£20	£100	16.7%
£150	£20	£130	13.3%
£200	£20	£180	10%
£250	£20	£230	8%

*Before any taxes, destination charges, resort fees or other costs that are not covered by the referral discount.

The referral code may be particularly useful for:

A one-night city break
Airport accommodation
A spontaneous weekend away
A hotel after a concert or event
An unexpected business trip
A last-minute change of travel plans
An overnight stay when public transport is unavailable
A UK staycation
A hotel booking before an early flight

What Types of Hotels Are Available?

HotelTonight uses its own descriptive hotel categories to make browsing easier. These categories focus on the style and experience of the property rather than relying only on conventional star ratings.

Luxe

Luxe properties are more upmarket hotels that may provide premium facilities, stylish rooms, enhanced service and additional comfort.

This category may suit travellers looking for:

Luxury city hotels
Premium resorts
Spa facilities
Upscale restaurants and bars
Higher-end rooms and suites

Hip

Hip hotels are fashionable, design-led or distinctive properties. They may include modern boutique hotels and accommodation in popular city neighbourhoods.

These properties can appeal to travellers who value:

Contemporary interiors
Independent character
Interesting communal spaces
Popular bars or restaurants
Central or fashionable locations

Solid

Solid hotels are dependable properties offering the main facilities most guests expect. They may not be the most luxurious options, but they can provide a comfortable and practical stay.

Basic

Basic properties concentrate on essential accommodation with fewer additional facilities. They can suit customers who mainly need a clean and convenient place to sleep.

Charming

The Charming category can include smaller hotels, guest houses, inns and bed-and-breakfast properties with a more personal or traditional feel.

Crashpad

Crashpad properties are budget-focused hostels, inns or simple accommodation. These may be suitable when price and location matter more than additional facilities.

High Roller

High Roller listings cover premium suites, penthouses and particularly luxurious accommodation for customers seeking a special stay.

HotelTonight’s official descriptions distinguish between Luxe, Hip, Solid, Basic, Charming, Crashpad and High Roller properties, helping customers search by atmosphere and service level.

Is HotelTonight Only for Last-Minute Bookings?

No. The name reflects how the service began, but HotelTonight is no longer limited to rooms booked on the day of arrival.

The app allows customers to book:

For the same night
For the following day
For a weekend break
Several weeks ahead
Up to 100 days before check-in

This makes HotelTonight useful for both spontaneous and planned travel.

Last-minute rates can sometimes fall when hotels have unsold rooms. However, waiting does not guarantee a lower price. Rates can also increase, and popular hotels may sell out.

If you find a hotel, location and price that suit your plans, booking earlier may provide more certainty.

HotelTonight’s UK app listing confirms that rooms can be booked for tonight, next week or up to 100 days in advance.

What Is the HotelTonight Daily Drop?

Daily Drop is a personalised hotel offer available within the HotelTonight app for selected searches.

When a Daily Drop is available, you can reveal the offer and receive a limited period in which to book it. The deal is typically available for only 15 minutes after it is unlocked.

The hotel is revealed before you book, allowing you to review important information such as:

Hotel name
Location
Photographs
Facilities
Guest feedback
Room information
Final price
Cancellation conditions

HotelTonight advertises Daily Drop savings of up to 30%, although the actual saving depends on the destination, dates, hotel and availability. Only one personalised Daily Drop is generally available per day where the feature is offered.

Can FNISAR be combined with a Daily Drop?

HotelTonight generally states that promotions cannot be combined. The app will determine whether the FNISAR referral code can be applied to a particular Daily Drop booking.

Check the checkout screen rather than assuming that both offers will stack. Use whichever eligible option produces the best final price.

What Is HT Perks?

HT Perks is HotelTonight’s loyalty programme. It rewards customers based on their lifetime qualifying spend through HotelTonight.

Everyone begins at the first level. As customers make more bookings and their qualifying spend increases, they may unlock additional discounts and rewards at participating hotels.

Possible HT Perks benefits include:

Access to additional app discounts
Special Perks Deal rates
Improved discounts at selected hotels
Credits at higher membership levels
The option to use certain discounts immediately
The option to save some eligible discounts for a later stay

HotelTonight says members do not lose their HT Perks status once they have reached a level, although specific benefits and programme conditions can change.

At Level 1, eligible app users may receive an additional 5% discount on participating rates. Higher levels can unlock different offers based on qualifying lifetime spend.

Using the HotelTonight referral code FNISAR for your first booking can therefore be the starting point for building your HT Perks activity.

Earn Airbnb Credit Through HotelTonight

Eligible HotelTonight customers in the UK may also be able to earn Airbnb credit from their completed HotelTonight stays.

Under the current programme, users can earn Airbnb credit worth 10% of the qualifying HotelTonight booking value, excluding taxes and fees. After completing a stay, the customer is prompted to connect an Airbnb account to claim the credit.

Once connected, eligible credit from future HotelTonight stays can be added to the linked Airbnb account automatically.

Important points include:

The benefit is available to eligible UK and US customers.
Credit is based on the qualifying booking value before taxes and fees.
The hotel stay must be completed.
A valid Airbnb account must be connected.
Airbnb credit generally expires one year after the relevant HotelTonight checkout date.
The programme and earning rate can change.

Airbnb announced the benefit for UK and US travellers, with eligible customers receiving 10% of the HotelTonight booking value in Airbnb credit after completing their stay.

This benefit is separate from the immediate £20 saving available through referral code FNISAR. Check both offers’ current conditions when booking.

HotelTonight Prices and Fees

The initial nightly rate is not always the complete amount you will pay.

The final checkout price may include:

The room rate
VAT or local accommodation taxes
Occupancy taxes
HotelTonight fees
Destination or resort fees
Charges collected directly by the hotel
Additional guest fees
Parking
Breakfast
Pet fees
Security or incidental deposits

HotelTonight displays applicable taxes and fees before the booking is confirmed, although certain charges may be payable directly to the hotel.

When comparing prices with another booking platform, compare the complete stay price, not only the headline nightly rate.

HotelTonight Price Guarantee

HotelTonight offers a Price Guarantee for qualifying bookings.

If you complete a booking through HotelTonight and find an eligible lower price elsewhere for the same hotel room, you may be able to claim HotelTonight credit equal to the difference.

The comparison normally needs to match important booking details, including:

The same hotel
The same stay dates
The same room type
The same number of guests
The same currency
The same cancellation conditions
The same included extras
A publicly available rate
A price available for immediate booking

The deadline for finding and reporting the lower price depends on when the booking was made:

Same-day bookings have a shorter claim window.
Next-day stays may have a deadline ending at midnight.
Bookings further in advance may provide a longer claim period.

Full Price Guarantee terms should be checked immediately after booking because claims are time-sensitive.

Are HotelTonight Bookings Refundable?

Many HotelTonight bookings are non-refundable, non-cancellable, non-transferable and non-modifiable.

This is one of the most important things to understand before completing a booking.

HotelTonight may be able to offer lower rates partly because the customer commits to the reservation. If your plans change after booking, you may not be entitled to:

Cancel the room
Move the booking to another date
Change the hotel
Transfer the reservation
Receive a refund
Receive promotional credit

HotelTonight confirms that most rooms are offered on a restrictive basis unless different conditions are shown at checkout.

Look for the Cancellable badge

Selected hotels offer cancellable rates through the app. If flexibility is important, look for the Cancellable badge and read the deadline and conditions carefully.

Do not rely on the badge alone. Open the complete cancellation policy before payment and take a screenshot if necessary.

Can You Choose Your Room Type?

Sometimes.

Certain bookings allow customers to choose between available room configurations, such as one bed or two beds. At other properties, the hotel assigns the room at check-in.

If a particular bed type, accessible room or other feature is essential, confirm it before booking or contact the hotel directly.

Requests such as the following may be subject to availability:

Twin beds
Double bed
Accessible room
High floor
Quiet room
Adjoining rooms
Early check-in
Late checkout
Cot or additional bed

A request is not necessarily guaranteed unless it is expressly included in the confirmed booking.

Is HotelTonight Good for UK Travellers?

HotelTonight can be especially useful for UK travellers who are flexible about the hotel they choose and want a quick way to compare a curated selection.

Potential UK uses include:

A spontaneous London break
A weekend in Manchester, Edinburgh or Liverpool
Accommodation after a wedding
A hotel near an airport
A business stay arranged at short notice
An extra night following a cancelled train
A theatre or concert trip
A domestic staycation
A last-minute anniversary break

Availability varies significantly by destination. Large cities and popular travel locations may have more options than smaller towns.

HotelTonight App Features

The app includes several tools intended to make finding and booking a room easier:

Same-day hotel searches
Advance bookings up to 100 days ahead
Location and neighbourhood search
Map-based browsing
Hotel style categories
Price and facility filters
Guest ratings and photographs
Pet-friendly filtering
Parking and Wi-Fi information
Daily Drop offers
HT Perks discounts
Cancellable-rate labels
Favourite hotels
In-app booking management
Access to customer support
Promotional-code redemption

HotelTonight markets the booking process as fast enough to complete in just a few taps, although you should still take time to check the dates, location, fees and cancellation terms.

Tips for Getting the Best HotelTonight Deal

Compare the total price

Check the same hotel on its direct website and at least one other reputable booking platform. Include all taxes, fees and extras.

Search nearby neighbourhoods

Moving your search slightly outside the most expensive central area may produce a better hotel or lower price.

Remember to consider the cost and time of travelling from the hotel to the places you want to visit.

Check more than one date

If your plans are flexible, compare different arrival days. Hotel rates can change substantially because of events, weekends and local demand.

Use filters carefully

Filtering for every possible facility can remove otherwise suitable hotels. Start with the features that are genuinely essential.

Read the latest reviews

Look beyond the overall score and pay attention to recent comments about:

Cleanliness
Noise
Location
Room size
Service
Wi-Fi
Air conditioning
Building work
Additional charges

Review the address

HotelTonight may show nearby properties when there is limited availability in the searched destination. Check the full address before booking.

Compare Daily Drop with the referral discount

A Daily Drop may offer a larger discount, but it may not combine with referral code FNISAR. Compare the final payable amount under each eligible option.

Check the code before paying

Make sure the £20 discount is visible before confirming your first booking. A referral discount usually cannot be applied retrospectively.

Consider cancellation flexibility

A slightly more expensive cancellable room can be better value than a cheaper non-refundable booking if your plans are uncertain.

Is the code only for new customers?

Yes. The £20 referral offer is intended for customers making their first HotelTonight booking.

Does a booking of exactly £100 qualify?

The offer is described as applying to a first booking over £100. To avoid missing the discount, select an eligible booking with a qualifying room value above £100 before taxes and fees.

Do taxes and fees count towards the £100 requirement?

Promotional minimums normally apply to the eligible room price excluding taxes and fees. The app will confirm whether your selected booking qualifies.

Can I apply the code after booking?

Usually not. Enter and apply FNISAR before payment. Confirm that the discount appears in the final checkout breakdown.

Can I use FNISAR on the HotelTonight website?

HotelTonight provides some web booking features, but referral and app-only rates may require the mobile app. For the best chance of receiving the offer, download the app and apply the code there.

Can I combine FNISAR with another promotion?

HotelTonight normally allows only one promotional code per booking. The checkout will show which discounts are eligible.

Can I combine the referral code with a Daily Drop?

It may not be possible because promotions generally cannot be combined. Compare the final prices and choose the best eligible offer.

Does the code work on every hotel?

No discount code is guaranteed to work on every property or rate. The booking must satisfy the referral conditions and any restrictions displayed by HotelTonight.

Why is the referral code not working?

Possible reasons include:

The code was entered incorrectly.
You have booked with HotelTonight before.
The booking value is not high enough.
Taxes and fees have taken the eligible room subtotal below the threshold.
The property or rate is excluded.
The code has expired or reached its usage limit.
Another promotion is already applied.
The same device or payment method is associated with an existing customer.
The booking is in an ineligible currency or location.

Check the spelling carefully: FNISAR.

Can I cancel a booking made with the code?

Only if the selected rate allows cancellation. Many HotelTonight reservations are non-refundable and cannot be changed.

How far ahead can I book?

How many nights can I book?

Stays of up to 14 nights may be available.

Can UK users earn Airbnb credit?

Eligible UK HotelTonight customers may receive Airbnb credit worth 10% of the qualifying booking value after completing their stay and linking an Airbnb account. Terms apply.

Does the referrer receive anything?

This is a personal referral code. The referrer may receive HotelTonight credit or another referral benefit after an eligible new customer uses the code and completes the required booking conditions.

Is the HotelTonight Referral Code Worth Using?

Yes—if you are a new HotelTonight customer and have found an eligible hotel booking over £100, using referral code FNISAR is an easy way to reduce the price by £20.

HotelTonight is particularly useful for travellers who value:

Fast mobile booking
Last-minute availability
Curated hotel results
Short city breaks
App-exclusive deals
Loyalty discounts
Flexible destination choices

The strongest value may come from combining the initial £20 saving with HotelTonight’s wider features, such as HT Perks, Daily Drop and eligible Airbnb credit. However, separate promotions may not stack on the same booking.

Before paying, confirm that the discount has been applied, compare the complete price with other booking options and read the cancellation policy carefully.
